Not sure if this question has been done on here before, if it has then I guess this thread will die and go away and that's cool too. Most people are saying that the fact that you have to wait 30 minutes after eating to swim is an old wive's tale and it's not true. Well me personally, I get terrible cramps if I don't wait. I was just wondering if anybody else found the tale to be true and get cramps and how many people can eat and then immediately swim with no adverse effects. There's a typo in the poll...it's *has, not is

    During exercise the capillary beds of the skeletal muscles take priority over the capillary beds of the digestive system/smooth muscle (Arterioles in the capillaries constrict in the digestive area while those in the skeletal muscles open). If you exercise less than 30 minutes after eating there will likely be semi-digested food/bolus rolling around in your stomach. I have done this on more than one occasion and things seemed to work out fine. Individual experiences may vary.
